The metal rods slide into the sides of the compressed paper chain pots and are then used to pull the chain pots apart so you can place them onto the spreader frame. The spreader rods can be removed after the paper chain pots are secured on the spreader frame. If your farm is doing a lot of transplanting, then you may want more than one set of spreader bars to allow multiple people to fill flats.
The spreader bars are a REQUIRED component of the paper pot system. You can’t use the paper chain pots without these.
This item is one pair of spreader bars.
Our Paper Pot System Starter Kit includes one pair of spreader bars, which may be a better choice for new paperpot users.
